About:
tmux is a terminal multiplexer that enables multiple virtual terminals to be created within a single terminal window. It allows users to split a terminal into panes and manage multiple sessions, persisting running applications even when the user disconnects. This tool is essential for maintaining long-running processes and organizing complex development workflows.
Key Features:
  • Session persistence: Detach and reattach sessions from any location
  • Window and pane splitting: Divide terminals into multiple regions
  • Multiplexing: Run multiple terminal sessions from a single window
  • Scriptable: Configure and control via command line
  • Vi/Emacs key bindings: Supports familiar navigation modes
Use Cases:
  • Managing long-running server processes or builds on remote machines
  • Organizing multiple development projects and tools in split panes
  • Pair programming by sharing a single terminal session
  • Maintaining workflow state over unstable network connections
Alternatives:
  • screen – Older GNU utility with similar features but less modern configuration
  • zellij – Modern alternative with Rust implementation and built-in plugin system
  • iTerm2 – macOS terminal emulator with some multiplexing features, but not a tmux replacement
